Simpson was acquitted of both murders in 1995 but is still widely suspected of the crime.

Pardo told the Los Angeles radio station: "I know who did it and I knοw why they did it.

OJ Simpson's former manager has claimed that he knows who is responsible for killing Nicole Brown Simpson and Ronald Goldman in 1994

"I just can't disclose it right now."

Pardo said that he and Simpson had not disclosed the information to authorities at the time because when they tried to speak with police, "they took all my stuff regarding the incidents".

He claimed officers were already looking into the information when they raided his office.

In an interview with People Magazine, Pardo said Simpson, who is in prison for an unrelated robbery conviction, "isn't losing any sleep" over the fact police were now examining the knife which was found by a construction worker, then passed to a now, former police officer, who stored it until earlier this year.
